I don't know if we've covered this. Forgive me.
For Reference, I have a G17 Gen5 that I only use to shoot GSSF matches.
Was at the LGS early yesterday few people were there, the gunsmiths were testing out a full auto and in the bay next to mine was the Glock rep, bringing all the store employee up-to-date on the new Gen 6. I stuck my nose in and asked if I could shoot the G17. If you didn't know the Gen 6 has:
A flat faced trigger design
redesigned optic mount more compatible with the industry.
palm swell
extended thumb rest
enlarged beavertail
new grip texture
slide serrations angled deeper into the slide
Yes I do like the trigger. Dry fired it very slowly several times. Acceptable creep. Reset was positive and not to long. The gun felt good. Understand I go back and forth between a Ruger 22/45, L/N frame revolvers, Sig P320, FN509 and others so the palm swell and grip angle aren't a biggie to me. The tang and texture are not of a concern. They did feel good. And one can always use a better grip on the slide. Just shoot in the rain and you'll see. I've learned to adapt. For others it's critical. The gun felt good. He had a 7yd target and I put the 10 rounds all in one hole for him. I didn't shoot too slowly after the first couple, either. I think he was going to save that target for bragging on the gun. I didn't pay attention to the iron sights since he had a red-dot on it and I don't care because I'd replace them anyway with LPAs.
I'm not going to run out and buy one. If on the off chance I win a gun at GSSF, I'll will up grade my Gen 5, but then by the time I do that they may have a Gen7 out.
